CYCLOMETER.

SPECIFICATION forming part of Letters Patent No. 447,540, dated March 3, 1891.

Application filed September Z0, 1890. Serial No. 365,637. (No model.)

To @ZZ whom it may concern:

Beit known thaty 1, EDWARD R. DE WOLFE, a citizen of the United States, residing at the city, county, and State of New York, have invented a new and useful improvement in Oyclometers, of which the following is a specification.

Oyeloxneters and o dometers for indicating the distance traveled over reads by vehicles have heretofore been employed. These instruments have been of various kinds, among which may be mentioned gravity-hub cyelometers, such as are illustrated and described in Letters Patent No. 270,737, dated January 16, 1883, and No. 357,758, dated February 15, 1887.

My invention relates to improvements in gravity-hub cyclometers of the class herein mentioned; and the object of my invention is to provide improved devices for imparting a regular positive and step-by-step motion from the rotatable axle of the vehicle to the train of registering mechanism, which in turn opcrates the hands of the visual dials recording the distance traversed.

In carrying out my invention I employ, in connection 'with a train of gears, theirk ,case and dials, the housing and countenbalance and a divided sleeve around the axle, a radially-slotted disk or f Geneva wheel having a pin or roller adapted to operate a toothed wheel of the train,which moves in a plane at right angles to that of the Geneva wheel. The said Geneva wheel receives a step-by-step progressive movement from a pin parallel with the rotatable axle of the vehicle, the periphery of the Geneva wheel being within a circumferential groove in the divided sleeve upon the axle, and the aforesaid pin extending across said groove to enter the radial slots of the Wheel to turn the same one notch each revolution of the axle and sleeve.

In the drawings, Figure 1 is a plan view of the apparatus with the dials and hands removed. Fig. 2 is a section and partial elevation of the same. Fig. 3 is a plan view of the dials in their relative position to Fig. 1. Fig. 4 is an elevation, and Fig. 5 a plan view, of a slight modification.

a represents the rotatable axle of a vehicle, preferably a bicycle or similar veloeipede.

b h represent the parts of the divided sleeve, adapted to freely surround the axle a and to be held together, as usual, by screws.

c c represent the parts of the housing, also 5 5 adapted to be held together by screws.

/ The stern d and counter-balance or weight d are connected together and to the housing c, and the said weight serves to so balance the indicating mechanism and its case as to 6o keep the dial g in a horizontal position.

I employ a hermetically-closed case connected te the housing c, such as is shown in Letters Patent Nos. 839,891 and 357,758, to inclose the train of registering mechanism, and the plates c e and sides ci3 form part of this case and serve to retain the train of registering mechanism, and the pivots of the arbors of said train are in said plates.

The gears and notched wheels f, f', f2, f3, 7o f4,f5,f6,f7,f8, and ff constitute the train of registering meehanis1n,which, being similar to those heretofore employed and not constituting an essential feature of my invention, do not require further description.

The special features of my invention are the following:

7L represents a radially-slotted disk or Geneva wheel mounted upon a short shaft or pin in the bearing-block c?. The bearing- 8o block c2 is fastened to the plate c and is between the plates c c', and the plate e is slot-ted for the wheel 7i to pass through and below the same. The half sleeves b b at their center have circumferential iianges 112 b3, be- 85 tween which a groove 2 is formed with a depressed portion er recess 3, and a pin 1 is secured in the flanges b2 b3 and passes across the groove 2 above the central portion of the depression 3. This groove 2 is slightly wider 9o than the thickness of the wheel 7i, and the lower edge of said wheel is received in said groove, the periphery of the wheel being curved between the radial slots to conform generally with the are of the divided sleeve. The points of the wheel 71, come Within the path described by the pin l, and as the said pin 1 revolves with the sleeve and axle a it enters the notches ofthe wheel 71, one at a time, passing in and out of the notches and turning the said wheel 7i one-fifth of a revolution each rotation of the axle a. A pin or stud and IOO roller 7L are connected to the face of thcivheel h and the same rotates with said wheel; but the circle of rotation is small, as said pin is near the center of said Wheel.

t' is a toothed wheel, and t" a pinion upon the arbor 2. This Wheel and pinion revolve upon a plane at right angles to that of the Geneva wheel, and are operated by the pin h', engaging the teeth of the wheel "i in succession and moving the same one tooth at a time by its step-by-step motion, and the pinion i engages and operates the wheels of the train-registering mechanism.

The pin or stud and roller 7L as a device for transmitting the motion of the Geneva Wheel h to the Wheel 'i may be dispensed with, and in lieu thereof the shaft of the Geneva Wheel h may be continued as a Worm-wheel similar to that shown at b in Letters Patent No. 339,891, herein referred to, and this Worm- Wheel would in turn operate a toothed wheel, such as t', and actuate the train of gearing.

In Fig. l the teeth of the Wheelt' are shown as of ordinary construction and acted upon by the pin 7L', While in Figs. 4 and 5 the teeth of the modified wheel t' are parabolically formed and are acted upon by a stud and roller h. This form is advantageous, because less friction is created in use.

Uponthe arbor 2 of the toothed Wheel t' I prefer to employ a curved spring-metal friction-plate m, with serrated outer edges that bear against the under side of the upper plate c. This plate m creates a friction that prevents jar from shift-ing the train-registering mechanism, but does not prevent the free operation of the mechanism by the wheel h.

I provide a bell 0r gong n, connected by a post n to the plate e and a hammer and hammer-Wire 0, and spring-Wire o2 is connected to a post 0 upon 'the plate e. The arbor of the wheel f2 of the train-registering mechanism extends through the plate e and carries a cam 7*, the revolution of which periodically operates the hammer-Wire o to sound the bell preferably at the end of every registered mile.

I claim as my inventionl. The combination, with the registering mechanism,a case inclosing the same, a housing connected to said case, and a Weight attached to and suspended from the housing, of a sleeve for the rotative axle of the vehicle, a pin in said sleeve, a radially-slotted disk or Geneva wheel mounted in and projecting through the lower plate of the case Within the housing and adapted to be operated by the pin of the sleeve, and devices connected to the Geneva Wheel for imparting a step-bystep movement to the train-registering mechanism,substantially as set forth.

2. The combination, With the registering mechanism, a case inclosing the same, a housing connected to said case, and a Weight attached to and suspended from the housing, of a two-part sleeve b-b upon the rotative axle of the vehicle, having circumferential flanges b2 b3, between which is a groove 2 and a depressed portion 3, a pin l, secured in the flanges b2 b3 and extending across the groove, and a notched disk adapted to be rotated by the engagement of the pin l to operate the train-registering mechanism, substantially as set forth.

3. The combination, with the train-registering mechanism, a case inclosing the same, a housing connected to said case, and a weight attached to and suspended from the housing, of the two-part sleeve I) b', having flanges b2 b3 and a groove 2 and depression 3, the pin l, the radially-slotted disk or Geneva Wheel 72, the pin or roller 7L upon said Wheel, the block e2, the toothed Wheel t, and pinion fi', the parts being constructed and operating in substantially the manner and for the purposes set forth.

4. The combination, with the registering rnechanism,a case inclosing the same, a housing, and a weight attached to and suspended from the housing, of a sleeve upon the rotative axle, flanges thereon, and a pin l, a radially-slotted or Geneva wheel z, operated by the pin I to set in motion the train-registering mechanism, a bell and its hammer connected to the case, and a cam upon an arbor of the registering mechanism for periodically sounding' the bell, for the purposes and substantially as set forth.

Signed by me this 15th day of September, A. D. 1890.
